New telescopes to help astronomers acquire sharper black hole images

New telescopes to help astronomers acquire sharper black hole images

Science
May 6 (UPI) -- Earlier this year, scientists captured the first up-close image of a black hole. Now, researchers are working on plans to produce even sharper images of the cosmic phenomena. Scientists published their plans for acquiring better black hole images this week in the journal Astronomy and Astrophysics. The plans involve the deployment of two or three coordinated orbital radio telescopes. To showcase the power of their planned constellation of observatories, dubbed the Event Horizon Imager, researchers developed a model to simulate the telescopes' image-making abilities. "There are lots of advantages to using satellites instead of permanent radio telescopes on Earth, as with the Event Horizon Telescope," Freek Roelofs, a PhD candidate at Radboud University in the Netherlands, s...
First ever black hole image released

First ever black hole image released

Science
Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. Details have been published today in Astrophysical Journal Letters.It was captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes.Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87."What we see is larger than the size of our entire Solar System," he said.

UK team drills record West Antarctic hole

UK team drills record West Antarctic hole

Science
Media playback is unsupported on your device UK scientists have succeeded in cutting a 2km hole through the West Antarctic Ice Sheet to its base. It's the deepest anyone has gone in the region using a hot-water drill. The British Antarctic Survey (BAS) pulled up sediment from the bottom of the hole and deployed a series of instruments.The researchers hope the project's data can help them work out how quickly the White Continent might lose its ice in a warming world. Dr Andy Smith leads the team, which is still at the drill site at a location known as the Rutford Ice Stream.He says there is immense satisfaction at having reached the bed after so many years of trying. An aborted atte...
Galactic collision could wake up Milky Way black hole

Galactic collision could wake up Milky Way black hole

Technology
New research has predicted that a galactic collision could wake the black hole at the centre of the Milky Way and cause it to swell ten times over and devour all surrounding matter. Astrophysicists at Durham University have predicted that the collision between the Large Magellanic Cloud (LMC) and our own galaxy could occur much sooner than the expected crash between us and neighbouring galaxy Andromeda.This "catastrophic" collision could occur in two billion years' time - much sooner than the expected eight billion years until we smash into Andromeda.This is because recent research has discovered that the LMC contains far more dark matter than previously thought - meaning it is losing energy and dooming it to crash into our galaxy. The findings are published in the jour...
